3D printed nylon polymer lamp generates power through rotation

Dec.15, 2012

The 3D printed shell of the Momentum light designed by architect Dr. Margot Krasojević produces an electrical current from kinetic energy. It is 3D printed with nylon ploymer and is suspended by a spindle whereby it's weight and form contribute to the angular momentum vector as it spins along its axis of rotation.

The light has a motion sensor diode clamped between both suspended 3d printed sections which powers the battery lighting the LED when in motion. It is affected by minor environmental changes such as temperature and air currents which rotate the light along its path of velocity. As the light rotates faster, the LED lights brighter.

The light weighs 145g and has glaze finish to minimize air resistance. It is comprised of two vertical elements which lock into one another using clamps, the LED light gets brighter as the speed of rotation increases.

The light also is being adapted to line the inside of the printed elements with copper coil. Using powerful magnets attached to the spindle and a separate magnet can also induce an electric current that powers the onboard LED.
